<h1>ov_bitrate</h1>

<p><i>declared in "vorbis/vorbisfile.h";</i></p>

<p>This function returns the average bitrate for the specified logical bitstream.  This may be different from the <a href=ov_info.html>ov_info->nominal_bitrate</a> value, as it is based on the actual average for this bitstream if the file is seekable.
<p>Nonseekable files will return the nominal bitrate setting or the average of the upper and lower bounds, if any of these values are set.

<h3>Parameters</h3>
<dl>
<dt><i>vf</i></dt>
<dd>A pointer to the OggVorbis_File structure--this is used for ALL the externally visible libvorbisfile
functions.</dd>
<dt><i>i</i></dt>
<dd>Link to the desired logical bitstream.  For nonseekable files, this argument is ignored.  To retrieve the bitrate for the entire bitstream, this parameter should be set to -1.</dd>
</dl>


<h3>Return Values</h3>
<blockquote>
<li>OV_EINVAL indicates that an invalid argument value was submitted or that the stream represented by <tt>vf</tt> is not open.</li>
<li>OV_FALSE means the call returned a 'false' status, which in this case most likely indicates that the file is nonseekable and the upper, lower, and nominal bitrates were unset.
<li><i>n</i> indicates the bitrate for the given logical bitstream or the entire
   physical bitstream.  If the file is open for random (seekable) access, it will
   find the *actual* average bitrate.  If the file is streaming (nonseekable), it
   returns the nominal bitrate (if set) or else the average of the
   upper/lower bounds (if set).</li>
